When fluid under pressure is delivered from the pilot valve to the right end chamber of the directional valve, spool 1 of the valve is shifted to the left, shutting off fluid delivery through port e to the power cylinder. Owing to overlap a, the machine tool table dwells in its extreme position. As the fluid flows out of the left end chamber b of the directional valve, it passes through flow-control valve 2. This slowly increases the amount of fluid delivered to the power cylinder through port d and, as a result, the speed of the table accelerates smoothly in the return stroke.
